Well, I saw the original Scientist model and I decided to improve it, because it was... 

well, it was fine, but It wasn´t good enough, so I resized his body, his head, his arms, remade its rig, down sized the texture, etc...

So here is the improved version of it.

******NOTE: If you downloaded this model after the current Revision, you may re download it, because I fixed a lot of errors.
